Turn 2: Varis
Varis Normal Summons "Gateway Dragon" (1600/1400). Varis activates the effect of "Gateway Dragon", Special Summoning a Level 4 or lower DARKDragon monster from his hand. He Special Summons "Sniffer Dragon" (800/400). As "Sniffer Dragon" was Special Summoned, Varis activates its effect, adding another copy of "Sniffer Dragon" from his Deck to his hand. Varis activates the effect of "Defrag Dragon" in his hand, sending another monster from his hand to the GY to Special Summon it. He sends "Background Dragon" to the GY to Special Summon "Defrag Dragon" in Attack Position (1000/600). Varis uses "Gateway Dragon" and "Sniffer Dragon" to Link Summon "Twin Triangle Dragon" (1200/↓→) to the Extra Monster Zone. Varis activates the effect of "Twin Triangle Dragon", paying 500 LP to Special Summon a Level 5 or higher monster in his GY to a zone it points to, but it cannot attack this turn and has its effects negated (Varis: 4000 → 3500 LP). He Special Summons "Background Dragon" (1600/1800) to the zone the bottom-center Link Arrow of "Twin Triangle Dragon" points to. Varis uses "Twin Triangle Dragon", "Background Dragon", and "Defrag Dragon" to Link Summon "Topologic Bomber Dragon" (3000/↑↙↓↘) to the Extra Monster Zone. Varis Sets a card.

"Topologic Bomber Dragon" attacks "Altergeist Marionetter" (1600/1700). As Varis's monster attacked while she controls an "Altergeist" monster, Ghost Gal activates the effect of "Altergeist Kunquery", Special Summoning it (0/2400), then negating the attack. As "Kunquery" was Special Summoned, Ghost Gal activates its effect, negating the effects of a monster Varis controls while "Kunquery" is on the field. She negates the effects of "Topologic Bomber Dragon".

"Primebanshee" attacks Varis directly (Varis 3500 → 1400 LP). As another "Altergeist" monster inflicted battle damage to Varis, Ghost Gal activates the effect of "Kidolga", which lets her Special Summon a monster in Varis's GY to a zone "Kidolga" points to, but it cannot attack unless "Kidolga" attacked that turn. She Special Summons "Twin Triangle Dragon" (1200/↓→) to the zone the middle-left Link Arrow of "Kidolga" points to. "Kidolga" attacks Varis directly (Varis: 1400 → 400 LP). "Twin Triangle Dragon" attacks Varis directly, but Varis activates an unseen Trap Card, destroying "Kidolga", "Primebanshee" and "Twin Triangle Dragon". As "Primebanshee" was sent from the field to the GY, Ghost Gal activates its effect, adding an "Altergeist" card from her GY to her hand. She adds "Marionetter". Ghost Gal activates her Skill "Secret Cure", to excavate cards from her Deck, until she excavates a monster. That monster is added to her hand, both players gain LP equal to its ATK, and all other cards are sent to the GY. She excavates "Kunquery" (0/2400) and adds it to her hand.

Turn 4: Varis
Ghost Gal activates her face-down Continuous Trap Card "Altergeist Protocol". "Protocol" prevents the activation and effects of "Altergeist" cards on Ghost Gal's field from being negated. When Varis activates a monster effect, Ghost Gal can send another face-up "Altergeist" card she controls to the GY to negate the activation and destroy that monster. As Ghost Gal activated a Trap Card, Varis pays half his LP to activate "Red Reboot" from his hand (Varis: 400 → 200 LP), negating the activation of that Trap Card and Setting it, then Ghost Gal can Set a Trap directly from her Deck. "Red Reboot" also prevents Ghost Gal from activating Trap Cards for the rest of the turn after "Red Reboot" resolves. Ghost Gal Sets "Altergeist Camouflage". As he controls no monsters, Varis activates the effect of "Background Dragon" in his GY, Special Summoning itself and a Level 4 or lower Dragon monster from his hand in Defense Position, but "Background Dragon" is banished when it leaves the field. He Special Summons it (1600/1800) and the Level 2 "Sniffer Dragon" (800/400). As "Sniffer Dragon" was Special Summoned, Varis activates its effect to add another copy of "Sniffer Dragon" from his Deck to his hand, which he subsequently Normal Summons (800/400).

At this point, Varis enters the Data Storm. As his LP is 1000 or lower, Varis activates his Skill "Storm Access", randomly accessing a card within a Data Storm. Varis obtains "Topologic Trisbaena" and adds it to his Extra Deck.

Varis uses "Background Dragon" and both copies of "Sniffer Dragon" to Link Summon "Topologic Trisbaena" (2500/↙↑↘) to the Extra Monster Zone. Varis activates the effect of "Defrag Dragon" in his GY, banishing three other monsters with the same name from his GY to Special Summon it. He banishes three copies of "Sniffer Dragon" and Special Summons "Defrag Dragon" in Defense Position (1000/600) to the zone the bottom-left Link Arrow of "Topologic Trisbaena" points to. As a monster was Special Summoned to a zone "Topologic Trisbaena" points to, its effect activates, banishing that monster and all Spells/Traps on the field, then inflicting 500 damage to Ghost Gal for each of her cards banished by this effect, in this case three (Ghost Gal: 4000 → 2500 LP).
